Hi, I have a clarification question on the following statement in Section 8.1.1.6 of RFC3261 regarding when a proxy should send a 483 and whether the number of hops includes the destination hop.
"The Max-Forwards header field serves to limit the number of hops a request can transit on the way to its destination. It consists of an integer that is decremented by one at each hop. If the Max-Forwards value reaches 0 before the request reaches its destination, it will be rejected with a 483(Too Many Hops) error response." Consider the following flow: (mf=max-forwards) UA-A --- INVITE (mf=2) ---> Proxy-A ---- INVITE (mf=1) ---> Proxy-B ---- INVITE (mf=0) ---> UA-B In the flow above, should Proxy-B forward the INVITE with max-forwards=0 to UA-B or should it reject the request with 483? Thanks for your help in advance, YoungSun _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
